SumUp

Build SumUp payment integrations for in-person and online checkout — covering card readers, mobile POS apps, and the full Cloud API.

Want to add payments to your app? SumUp walks you through the whole process, whether you're ringing up sales at a physical register, letting customers pay online, or handling transactions behind the scenes through code. The plugin connects you directly to SumUp's live API and gives you everything you need to get started—pick from options like card readers for your phone, embedded checkout pages, server libraries in whatever language you code in, or even webhooks to track when payments come through.
